5 terms

restricted stock units ("RSUs") financial

"in connection with the vesting of restricted stock units ("RSUs")"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

tax withholding obligations financial

"sold by the Reporting Person to cover tax withholding obligations"

beneficial ownership financial

"may be deemed to share beneficial ownership of these securities"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"disclaims beneficial ownership of these securities except to the extent of her pecuniary interest"

co-trustee financial

"The Reporting Person is a co-trustee of the ACP 2021 Trust"
